INSULATOR.

To all whom it may concern:

Be it known that I, IRA HUNTER, a citizen of the United States, residingat Carlisle, in the county of Nicholas and State of Kentucky, haveinvented certain new and useful Improvements in Insulators; and I dodeclare the following to be a full; clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in insulators.

One object of the invention is to provide an insulator for line wiresadapted to be applied to a cross-arm or other support and to securelyfasten a wire thereto.

Another object is to provide an insulator of this character which willbe simple, strong, durable and inexpensive in construction, efficientand reliable in operation and which may be quickly and easily applied toa support and to the wire.

WVith these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a plan view of a portion of across-arm or similar support showing my improved insulator appliedthereto and in position for securing a wire; Fig. 2 is a side view ofthe cross-arm or support and an end view of the insulator as shown inFig. 1; Fig. 3 is a cross sectional view thereof taken on the line 33 ofFig. 1; Fig. 4 is a view similar to Fig. 3 illustrating the manner inwhich the wire is applied to the insulator after the latter is in placein the cross-arm; Fig. 5 is a detail perspective view of one of themembers of the insulator.

My improved insulator comprises a cylindrical body formed in twosections 1 and 2 each of which has formed on its outer end a head 3which may be of any desired shape and which is here shown as beingsubstantially of semi-oval form. The inner ends of the heads form abruptshoulders t which when the sections of the insulator are applied to across-arm or other support engage the outer sides thereof. In thesection 1 of the insulator is formed a longitudinally extending grooveor channel 5, disposed in a tangential plane a similar groove or channel6 being formed in the section 2. These Specification of Letters Patent.

grooves are arranged at slightly different positions in the two sectionsso that when the latter are turned in their supports the inner ends ofthe grooves or channels may be brought into alinement to form acontinuous passage through which the line wire L is passed when appliedto the insulator and as is clearly illustrated in Fig. 3 of thedrawings. Also formed in the insulator l is an eccentrically disposedlongitudinal passage 7 a corresponding passage 8 being formed in thesection 2. The passages 7 and 8 of the sections 1 and 2 of the insulatorare adapted to be brought into register when the sections of theinsulator have been turned to inclose the line wire in the grooves 5 and6 and when said passages 7 and 8 are thus brought into register abinding or fastening wire 9 is inserted therethrough and the ends of thewire 9 which project beyond the ends or heads of the sections are coiledor twisted around the line wire L adjacent to the ends of the heads 3and as is clearly indicated in Figs. 1 and 2 of the drawings. When thewire 9 is thus inserted through the alined passages 7 and 8 in thesections of the insulator said sections are locked against independentrotary movement and are thus held in position to fasten the line wirethereto.

In applying the insulator the cross-arm or other support S has formedtherethrough a bore or passage corresponding in diam eter to thediameter of the body of the insulator and in one side of the cross-armor support Sand extending in line with the center of the passagetherethrough is a transverse slot 10 which communicates with the passagethrough the support. The sections 1 and 2 of the insulator are insertedinto the opposite ends of the passage through the support until theshoulders 4 of the heads 3 come into engagement with the outer sides ofthe support as shown. The sections of the insulator are now turned inthe passage until the outer edges of the grooves or channels 5 and 6 arein alinement and register with the slot 10 as clearly shown in F ig, 4of the drawings. The line wire is now passed through the slot 10 andinto the alined outer portions of the grooves 5 and 6 after which thesections of the insulator are again turned in the proper direction tobring the inner portions of the grooves into alinement thus inclosingthe line wire in or between the inner ends of said grooves as clearlyshown in Fig. 3 of the drawings. This movement of the sections of theinsulater will bring the passages 7 and 8 therein into alinement andthrough the alined passages 7 and 8 is inserted the fastening wire 9.The wire 9 when thus inserted through the passages 7 and 8 lock thesections of the insulator against turning and in operative en agementwith the line wire as hereinbefore described. The ends of the fasteningwire 9 are then brought up and coiled or twisted around the line wire atthe ends of the insulator thus securing the fastening wire in positionas well as holding the sections of the insulator against longitudinalmovement and in operative engagement with the cross-arm or support S.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the claimed invention.

Having thus described my invention, what I claim is:

1. An insulator comprising a body formed in transverse sections, each ofwhich has a longitudinal tangentially disposed groove and a longitudinalpassage therein, the .grooves in said sections being disposed indifferent positions, so that when one of said sections is turned apredetermined distance, the inner portions of the grooves of the twosections will be brought into longitudinal alinement, the outer portionsthereof disposed out of alinement, and said passages brought intoalinement to receive a fastening wire.

2. An insulator comprising a sectional body portion having lateralshoulders on the outer ends of said sections, said sections beingsimilarly constructed with tangentially disposed longitudinal groovesformed therein and eccentric passages extending therethrough wherebywhen the sections are alined and turned a predetermined distance in onedirection, the outer portions of the grooves of the two sections arebrought into alinement and on further turning of the sections, the outerportions of the grooves will be thrown out of alinement and the innerportions brought into alinement to form a continuous passage for a linewire, and when said sections are turned to bring the inner portions ofthe grooves into alinement, the

passages in said sections will aline to receive a fastening wire.

3. The combination with a support having a passage extendingtherethrough and a slot opening through one side of the support andcommunicating with said passage, of an insulator comprising acylindrical body portion formed in transverse sections and adapted to beinserted and turned in the passage of said support, said sections havinglongitudinally extending tangential grooves therein and eccentricallyarranged longitudinal passages, said grooves being positioned in saidsections to provide for the alining of their outer portions when one ofthe sections is turned a predetermined distance and the alinement of theinner portion of said grooves when the section is turned further,whereby when the outer portions of the grooves are alined they aredisposed to reg-- ister with the slot in the support to receive a linewire, the alining of the inner portions of said grooves being efl'ectedwhen the outer portion of the groove of one of the sections is turnedsufliciently to remove the groove from registration with the slot in thesupport, the passages in said sections being brought into alinement whenthe inner portions of the grooves register.

4. The combination with a support having a passage extendingtherethrough, a slot opening through one side wall of the passage, of aninsulator comprising a cylindrical body formed in transverse sectionsand adapted to be inserted and turned in the passage in said support,said sections having longitudinally extending tangential grooves andeccentrically arranged passages therein, the grooves and passages insaid sections being similarly arranged so that when the inner ends ofthe sections are brought together or alined, the outer portions of thegrooves of the two sections will register and the inner portions beopposite from each other, the turning of one section a predetermineddistance serving to bring the inner portions of the grooves intoalinement and to throw the outer portions thereof out of alinement, thepassages in said sections being so disposed that the turning of thesections to bring the inner portions of the grooves thereof intoalinement will cause said passages to register and aline.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
